i just got back from a week of diving in cozumel and found some issues with my data some dives logged a dive temp of 48 some 79(which is right) some 84 and one -67. and i have one dive that will not download. i had a low battery icon when i arrived at cozumel so i had the battery changed hasn't been the same since. all other info looks right. computer is only 9 months old. should i just send it in for warranty repair? or not worry about it as its just a temp.
